Abstract:

The Front Cover image shows a single-step process that effectively depolymerizes lignin in supercritical ethanol using an inexpensive CuMgAlOx catalyst. Ethanol not only acts as a hydrogen-donor solvent but also as a capping agent, which can stabilize the highly reactive phenolic intermediates either by O-alkylation of hydroxyl groups or by C-alkylation of the aromatic rings, thus essentially inhibiting repolymerization reactions. High monomer yield can be obtained without char formation. The monomeric products can be used as fuel additives or chemicals.
